Hello,

At the end of last year, I had issues with getting ath10k to work with
the new IPQ4019. And I wanted to know if the was due to LEDE's patched
mac80211 or if this was problem in the mainline as well.

The attached patch allowed me to use the ath10k from the kernel
source to boot up the ath10k device. But as you can see, there 
were quite a few things that needed to be modified in order to
do it this way (Is there a better one?).

In any case, If you want to adapt it, I think you would have to
add a kmod-net-ath9k package (see mac80211-package's kmod-ath9k)
to it and do a few modifications to the AR71XX kernel config.
Have Fun!

(I hope patchwork doesn't pick this up. If it does, please delete it there.)
